Uridine treatment prevents myocardial injury in rat models of acute ischemia and ischemia/reperfusion by activating the mitochondrial ATP-dependent potassium channel

Scientific Reports, 2021
The effect of uridine on the myocardial ischemic and reperfusion injury was investigated. A possible mechanism of its cardioprotective action was established.

USB1 deficiency disrupts neutrophil maturation via RNA dysregulation independent of global pre‐mRNA splicing

Animal Models and Experimental Medicine, EarlyView.
This graphical abstract illustrates the essential role of USB1 in neutrophil maturation. In normal myeloid cells, USB1 acts as an RNA exonuclease, trimming RNA tails to maintain proper RNA network function, which supports the differentiation of myeloid progenitor cells into mature neutrophils.

Uridine affects liver protein glycosylation, insulin signaling, and heme biosynthesis. [PDF]

PLoS ONE, 2014
Purines and pyrimidines are complementary bases of the genetic code. The roles of purines and their derivatives in cellular signal transduction and energy metabolism are well-known.

Synergistische Entwicklungsstrategien von Inhibitoren gegen humane UDP‐Galactose‐4‐Epimerase

Angewandte Chemie, EarlyView.
Die Epimerase GalE ist essenziell für die Biosynthese von krebsrelevanten O‐GalNAc Glykanen. Wir verwenden orthogonales, strukturbasiertes Screening niedermolekularer Fragmente an, um kovalente und nichtkovalente Inhibitoren gegen GalE mit nicht mehr als 22 optimierten Verbindungen zu erhalten.

A Synergistic Inhibitor Development Strategy Against Human UDP‐Galactose‐4‐Epimerase

Angewandte Chemie International Edition, EarlyView.
The epimerase GalE is crucial for the biosynthesis of cancer‐relevant O‐GalNAc glycans. Here, we employ orthogonal, structurally enabled small molecule fragment screens to yield both covalent and non‐covalent inhibitors against GalE within no more than 22 elaborated compounds.

BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

Angewandte Chemie International Edition, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.
